After seeing Toruya's post, I double checked... and yes, he's right. She's actually Aoi Yume from Yume Senshi Wingman. I have to say, though, that she looks a lot like Yukime at first glance. Thanks for the correction; I've updated the list to reflect the change.

Base +7, grumpymal +30, tanaab1234567890 +10, dsax +27, slicerness +8, danixxx +31, Hentai Master X +7, Sushilicious +31, fufu1234 +4, Boneriffic +10, observer1980 +23, Floripes +11, Goldenerik +14, and 5 more...

I wish we had English translations of his works

Base +2, Hentai Master X +7, Sushilicious +31, observer1980 +23, xXMostWantedXx +7

I have been waiting for this.

Base +7, observer1980 +23, xXMostWantedXx +7

CORRECTION
no. 22-23 is NOT Yukime
it's The Character from Wingman
